The CSD95410RRB is a Texas Instruments NexFET smart power stage rated at 90 A peak continuous for synchronous buck converters. A smart power stage integrates the gate driver together with the high-side and low-side power MOSFETs in one package, replacing three separate devices and the routing between them. The CSD95410RRB is supplied in a 41-pin VQFN-CLIP package measuring 6 mm x 5 mm x 1 mm and is rated for -40 C to 125 C.

Smart power stages are the building block of multiphase core rails, where several phases each deliver high current into a processor, GPU, ASIC or memory supply that a single converter could not handle. At 90 A peak, the CSD95410RRB targets the highest-current phases in server, networking and computing power designs. Integrating the driver with the FETs shrinks the switching loop, cutting parasitic inductance and ringing so the converter can switch faster and more efficiently. Datacenter hardware, motherboard and accelerator board designers are the primary users, typically pairing these with a multiphase PWM controller.
